Title: Method for reducing iron ore in rotary kiln
Inventor: MOKLEBUST OLAV
IPC: C21B13/08
Filed: 1958-02-06
Abstract: Iron oxide is reduced by means of a large excess of solid carbonaceous reducing agent in a rotary kiln operating at sub-atmospheric pressure and heated by the introduction of preheated combustible gas at one end of the kiln in amount sufficient to avoid, as far as possible, the direct combustion of solid carbonaceous material, and oxygen containing gas introduced through side tubes distributed along the kiln, in an amount sufficient to give the desired temperature distribution in the kiln and to burn completely the combustible gas, the feed material occupying 25-45% of the kiln volume.  As combustible gas, petroleum gas, coal gas or water gas may be used, which may be indirectly preheated and may be completely burned before reaching the preheating zone at the charging end of the kiln.  Ilmenite, magnetite, or taconite ore may be reduced by this process, and they may be pelletised using 5% Na Cl as binder.  Five times the amount of reducing agent theoretically required may be used, the excess being separated from the reduced material and recycled.

Title: Improvements in or relating to products from foamed rubber latex
Inventor: PATON FREDERICK JAMES
IPC: C08J9/30
Filed: 1951-02-21
Abstract: In making products from natural rubber latex by compounding the latex with vulcanizing agents and a foaming agent, foaming the compounded latex by mechanical agitation, gelling the foam with an acid-forming, delayed-action agent, e.g. sodium silicofluoride, a titanofluoride, or a persulphate, and vulcanizing the gel, the latex is, before gelling, subjected to the action of a proteolytic enzyme for a time sufficient to increase the sensitivity of the latex to gelling without rendering it unstable to the mechanical agitation.  Latices gelling at pH not greater than 7.8 on addition of 0.5-1 per cent. of sodium silicofluoride are preferred; subjection of the latex to the action of the enzyme may be discontinued when the gelling pH so determined reaches 8.1-8.3. According to examples, ammonia-preserved rubber latex of 60 per cent. solids content is allowed to stand 12-24 hours with 0.05 per cent., based on the rubber, of trypsin, the latex is then compounded and castor oil soap is added, and is frothed by whipping, the froth is compounded further and sodium silico-fluoride is added, and the froth is allowed to gel.

Hydraulic transmission of power.-In a hydraulic device for controlling the stroke and speed of the reciprocating table c of a machine for internal grinding, a valve a controls entry of fluid to a cylinder actuating the table from a pipe 8. During normal working, pressure from a pipe 1 is admitted through pipes 4, 5, 6, 8 to the valve a, and stops d<1> and e on the carriage reverse the valve a, at the end of stroke, through a geared lever b, and a stop v<1> actuates a bell-crank z to centralize a spring-urged piston s which exhausts pressure from the back of a piston 26 by pipes 25, 30. Oscillation of the piston 26 actuates the crossfeed and moves a pawl 27 engaging a control cam 16. When a notch 22 in the cam 16 registers with a pawl 20 a lever 19 moves pistons p, q to the left and pressure through pipes 3, 9 moves a rod e<1>, Fig. 2, axially to cause the arm b to contact with a stop d<2> and the stroke of the table c is increased until the stop v through the bellcrank z moves the piston s to the left and pipes 2, 15, 11 are put under pressure to move pistons k, i to the right. The duct 6 is closed and pressure through a pipe 5 causes reduced carriage velocity, and at the same time pressure through a pipe 13 operates mechanism trueing the grinding wheel. The pawl 20 moves from the notch and the finishing operation is carried out with normal actuation of the table c until a projection 23 engages the pawl 20. The pistons p, q now move to the right and pressure from a pipe 10 moves the rod e<1> axially free from the stop d and the table c continues its travel until the stop v moves the piston s to the right, causing the duct 7 to be opened and the table to be moved at its highest velocity.

Abstract: 1390021 Controlling shearing machines WILKINS & MITCHELL Ltd 9 Feb 1972 [9 Feb 1971] 4298/71 Heading B3W A billet 19 with front and rear end portions of unacceptable quality is fed by rolls (only roll 14 shown) against a front stop 16. The feed rolls are stopped and, the stop 16 having been retracted, pinch rolls 28 feed the billet until the defective portion 20 is to the right of the shear plane of sheet 10, 11. Hold down 13 is actuated and then blade 10 shears off the defective portion. The hold down 13 is raised and the feed rolls 14 &c. feed the billet against a back stop 15 spaced from the shear plane by a distance equal to the length d of the identical pieces 22-27 into which the billet is to be divided. The cycle of feeding, clamping and shearing continues until a photo-cell 17, also spaced from the shear plane by distance d, detects the passage of the trailing end of the billet and thus that a portion remains which is between d and 2d in length. The stop 16 is raised to stop the following billet. A second photo-cell 18 is so positioned that, if the trailing end clears it, the portion 27, 21 does not include a portion long enough to be held by hold down 13 whilst the piece 27 is sheared from it. In this case, control means of the apparatus prevents further shearing taking place, the portion 27, 21 being pushed out by the following billet. Such portions may be fed to the shear from the delivery side with the piece 27 against the stop 16 and held by hold down 13 while the defective portion 21 is sheared off. If the trailing end does not clear the photo-cell 18 one more shearing stroke is carried out and the following billet ejects the defective portion 21. The position of the back stop 15 may be adjusted automatically in dependence on the weight per unit length of the billet signalled to the stop form weighing apparatus.

An apparatus for conveying articles G from a despatch point to a number of distribution points 1, 2, 3, whereby when the articles are despatched a destination signal is fed along a chain of stores S 1 , S 2 , S 3  . . . to actuate the appropriate article ejection ramps W 1 , W 2  or W 3 , and in which the transfer of signals between successive stores is arranged to occur after time intervals corresponding to the time taken for the conveyer B to move articles over corresponding sections of the conveyer. The conveyer comprises an endless belt B passing around end rollers R 1 , R 2  the roller R 1  having a pulse transmitter JG connected to it for rotation therewith. The destination signal associated with the despatched article is fed into a keyboard T and is transmitted into store S 1  once the article G has passed between a light source L and cell E. A counter Z 1  disposed between adjacent stores S 1 , S 2  is conditional to count, by an output signal from the store S 1 . The counter Z 1  has a capacity to receive the number of impulses from the pulse transmitter, JG corresponding to and in synchronism with, the travel of the conveyer between the light source and the ejection ramp W 1 . When full capacity of impulses is achieved an output signal from that counter operates the subsequent store S 2  causing the destination code to be transferred to S 2  and erased from store S 1 . The output signal from the store S 2  either operates a decoding device U 1 , if the destination code coincides, whereupon the ejection ramp W 1  is operated or a further counter Z 2  is operated and the series of events is repeated until one of the further decoding devices U 2 , U 3  is operated. If the distance between two delivery points 2, 3 is greater than the smallest spacing between two articles being conveyed, a buffer store S 4  is installed. The counters Z 3 , Z 4  associated with the store S 4  each simulate half the distance between the two points 2, 3. As many buffer items are required as the number of conveyed articles which can be present between successive delivery points.
